A kite is a quadrilateral with two pairs of adjacents sides of equal length. If the pairs have the same length, then the object is called a rhombus. Some authors restrict kites to being convex. However, a quadrilateral defined as above could be either convex or concave. Concave kites are often called arrowheads or darts. (Note: all rhobmi must be convex.) A kite has two sides of length a=b=7.9 and two sifes of length c=d=4.8 (all measured in yards). The angle between the largest sides is α=72∘. What is the area of this figure if it is convex?
